Roberta grows pea plants, some in shade and some in sun. She picks 8 plants of each type at random and records the heights. Shad

natita [175]

Answer: 2.6

Step-by-step explanation:

Step 1: Calculate the mean of Shade's plant heights.

= 7+12+12+8+9+8+8+8/8

= 72/8

Step 2: Calculate the range of Shade's plant heights. Range is highest minus lowest number. This will be:

12 - 7 = 5

Step 3: Calculate the mean of Sun plant heights.

19+24+20+23+24+23+23+20/8

= 176/8

= 22

Step 4: Find the range of Sun plants height.

= 24 - 19 = 5

Step 5: Find the difference of means

= 22 - 9

= 13

Step 6: Divide the difference of means by the range.

= 13 ÷ 5

= 2.6

For the ordered pair, give three other ordered pairs with θ between −360° and 360° that name the same point.

FinnZ [79.3K]

<h2>Answer: $(357^{0},330^{0})$ , $(-3^{0},-30^{0})$ , $(357^{0},-30^{0})$ </h2>

Step-by-step explanation:

For a ordered pair $(\alpha ,\beta )$ , $(\alpha -2n_{1}\pi ,\beta -2n_{2}\pi )$ represents the same point in the cartesian plane where $n_{1}$ and $n_{2}$ are any integers.

Given point is $(-3^{0},330^{0})$

Taking $n_{1}=-1,n_{2}=0$ ,

$(357^{0},330^{0})$

Taking $n_{1}=0,n_{2}=1$ ,

$(-3^{0},-30^{0})$

Taking $n_{1}=-1,n_{2}=-1$ ,

$(357^{0},-30^{0})$
